When I try to add a name to a folder using the emoji keyboard it's pretty hard, almost impossible, to swipe the keyboard to the next page.

Has anyone else encountered and/or fixed this problem?

Steps to recreate problem:
1. Enable emoji keyboard
2. Make a folder in any home screen
3. Edit the name of the folder
4. Switch the the emoji keyboard
5. Try to swipe to the other pages (and miserably fail!)

There have been lots of bugs on older iPhones with iOS 7, I have an iPhone 4, and this may be one of them. But if anyone has found a tip to fix it, please share.
